Description

Currently it's not possible to visually differentiate roles which only provide additional privileges from roles that can be used to login into the backend.
The description might provide some hints, but until now (Neos 8.3.16) the description is not even shown when creating users.

This leads to users often having multiple roles, though they don't even need them, or missing a role and support is necessary to get a user fully working.

Possible Solution

Highlight every role that has the Neos.Neos:Backend.GeneralAccess granted with a color or add another column Can login or similar in the roles list.
